Definitions
- the invention relates to the field of cleaning of compressors, in particular compressors of exhaust gas turbochargers for internal combustion engines. It relates to an air inlet housing of a compressor with an integrated cleaning device.
- Exhaust gas turbochargers are used to increase the performance of internal combustion engines (reciprocating engines).
- An exhaust gas turbocharger consists of an exhaust gas turbine in the exhaust gas stream of the internal combustion engine and a compressor in the intake tract of the internal combustion engine.
- the turbine wheel of the exhaust gas turbine is set in rotation by the exhaust gas flow of the internal combustion engine and drives the impeller of the compressor via a shaft.
- the compressor increases the pressure in the intake tract of the internal combustion engine, so that when sucking a larger amount of air enters the combustion chambers. It is known that in compressors of such exhaust gas turbochargers, the intake of polluted air can lead to contamination, in particular on the blades and the hub of the rapidly rotating compressor wheel.
- Fig. 2 shows the two most commonly used cleaning devices.
- the required amount of cleaning medium can be supplied to the flow channel for cleaning the compressor wheel at the appropriate time.
- the cleaning medium is detected by the flow and transported in the area of the blades of the rotating compressor wheel, where it can develop its cleaning effect.
- a container for the cleaning medium outside of the air intake housing - silencer or air intake - fixed This container is usually provided with a lid and connected via a valve with the flow channel. If the compressor is to be cleaned, the cleaning medium is filled into the container when the valve is closed. Thereafter, the container is closed with the lid and the outlet valve is opened. The cleaning medium then flows through a feed line and a tube into the flow channel in front of the compressor wheel.
- the container is pressurized to inject the cleaning medium.
- the container may be removably attached to the housing so that the container can be removed from the housing between two cleaning operations, for example to prevent the container mounted outside the housing from being damaged or simply taking up too much space.
- the object of the present invention is to simplify a cleaning device for a compressor of an exhaust gas turbocharger. According to the invention, this is achieved by integrating the container for the cleaning medium into an air inlet-side housing part, that is to say the silencer, the air intake pipe or the compressor housing itself. Thanks to the integrated solution, fewer components are required, which reduces the logistical effort during assembly. In addition, the external dimensions of the compressor, or the entire exhaust gas turbocharger can be reduced, which is favorable for the transport, the installation of the turbocharger on the engine and the service. In case of service and during transport there is no exposed cleaning device, which can be damaged. The device is more reliable because no moving parts are needed. The new solution can be realized both with suction with suction nozzle and with silencer. Further advantages emerge from the dependent claims.
- Fig. 1 shows a conventional exhaust gas turbocharger with compressor 1 and exhaust turbine 3, and arranged therebetween bearing housing 2.
- the exhaust gas turbine 3 includes a gas inlet 31 through which the hot exhaust gas flows to the turbine and this drives before the exhaust gas is supplied through the gas outlet 32 of the exhaust system.
- the turbine wheel is arranged at one end of a shaft rotatable about the axis A, which is rotatably mounted in the bearing housing 2.
- the compressor wheel At the other end of the shaft is the compressor wheel, which sucked through the air inlet 11 air compressed, which is then collected in a spiral or collector housing and fed via the air outlet 12 to the combustion chambers of the internal combustion engine.
- the sucked air can be supplied to the compressor via a tubular intake 6 or via a silencer 4.
- the muffler may additionally include filter elements which prevent the entry of larger particles into the compressor. In this case, we talk about a filter silencer.
- a compressor assembly with a conventional cleaning device For introducing the cleaning liquid into the flow channel, feeds 52 in the form of simple hoses or thin tubes are led into the flow region from radially outside the compressor housing or in an alternative embodiment, as used by certain compressor manufacturers, in the radially inner region of the flow channel. By means of these feeds, the required amount of a suitable cleaning medium can be introduced from a container 51 into the flow channel for cleaning the compressor wheel 10 at the appropriate time. The cleaning medium is detected in operation by the air flow and transported in the region of the blades of the rotating compressor wheel 10, where it is intended to effect a cleaning of the soiled surfaces.
- the container for the cleaning medium is not fastened separately to the compressor housing or to a mounted housing part, but integrated in one of the housing parts.
- the container 51 according to the invention in the compressor facing front wall 41 of the muffler 4 is integrated.
- the front wall 41 has an opening in the middle, through which the air flows to the compressor wheel.
- the opening may be circular or circular.
- the muffler comprises, in addition to the front wall 41, a rear wall 42.
- the front wall and the rear wall are connected to each other via ribs 47, wherein the entire muffler housing may be formed as a casting or composed of separate, assembled elements.
- the muffler further comprises protrusions 45 protruding from the housing walls, between which grooves 46 are formed, which serve to receive insulating elements.
- the sucked air flows accordingly in the radial direction in the region between the front wall and the rear wall, between the insulating elements and through the opening in the front wall towards the compressor.
- holes 44 are distributed along the circumference in a mounting flange.
- the container 51 is formed as part of the mounting flange, as shown in detail in the section parallel to the front wall by the mounting flange 43 and the container 51 according to Fig. 4 or the section perpendicular to the front wall through the container 51 according to Fig. 5 can be removed.
- the container 51 opens in a tubular feed 52 into the flow channel. By this supply, the cleaning medium from the container 51 is passed into the flow.
- a valve may be disposed between the container 51 and the feeder 52 for closing the conduit between the container and the supply, as needed, such as to prevent unfiltered air from being drawn in through the feeder and the container during operation of the compressor and pollutes the compressor or possibly causes unwanted noise.
- the container 51 is disposed on the compressor-facing side of the muffler.
- the container can also be embedded in the rear wall of the muffler, whereby about the accessibility for filling the container can be simplified.
- the container 51 is advantageously arranged in the upper region of the muffler.
- two or more containers 51 may be provided, each with its own or a common feed 52.
- large compressors can be used for cleaning on both sides arranged containers in operation, one or the other container, for example, if the accessibility should be limited on one side.
- the inventively integrated in the housing wall container has a filling opening, which can be closed with a plug, lid, cloth or other closure radially outwards, so that less dust sucked in and less sound exits.
- a sieve element 53 may be arranged which measures the flow of a Cleaning fluid allows, but sieves larger dirt particles and prevents it from entering the flow channel. Such a sieve element 53 thus also prevents clogging of the feed 52.
- the optional cover of the container 51 is removed. Thereafter, the cleaning medium is poured through the filling opening in the container. If no valve is present, the cleaning medium in the operating state of the compressor, that is to say with a rotating compressor wheel, is sucked out of the container and fed to the compressor. The suction effect is due to the lower pressure at the compressor inlet to the ambient pressure. Depending on the size of the compressor and / or degree of soiling, the cleaning process can be repeated several times.
- the container for the cleaning medium can be integrated in the intake stub according to the invention.
- the intake manifold is usually a cast workpiece whose manufacturing process has to be adjusted only slightly by the additional container.
- the cleaning container may also be located in an outboard, i. be arranged the silencer or the intake manifold facing housing wall of the compressor housing.
- This housing part is usually as well as the front wall of the muffler or the intake manifold a cast element, which can be easily adapted.
- the inventive integration of the container in one of the flow channel limiting housing parts in the region of the air inlet of the compressor means that no additional attachments for the cleaning of the compressor must be provided.
- a cleaning liquid can be used as a cleaning medium.
- a cleaning liquid can be used.
- water with or without special treatment such as cleaning or temperature control.
- the water can be used with or without cleaning additives.
- Alternatively or mixed with the liquid can be used as a cleaning medium granules.
- the inventive compressor cleaning is suitable for cleaning centrifugal compressors of exhaust gas turbochargers for internal combustion engines or other compressors.
